This problem seems to happen if there are more columns in one view than the other.

That is, if there are more columns configured in the 'Filter Columns' than in 'My Default' (or the other way around), JIRA will display all the columns configured plus the remaining ones:

• e.g.: If there are two configured for 'Filter' and 5 from 'My Defaults', JIRA will display the two from 'Filters' plus three from 'My Default'.

Steps to Reproduce

1. Create a filter;
2. Configure the filter's columns to display 5 (any) fields;
3. Configure the 'My Default' Columns to 7 fields;
4. Click on an issue to display the 'Issue View';
5. and then on 'Return to Search'.

Actual Behavior

The columns will be misaligned, as shown below:
